maybe you post other setups & resulting nadir...

This is a Nadir from Panoneed with y Canon 5D2 and a Nikon 35mm lens. 45 shots @20% overlap, sphere shot in about 3 Min, f8, 1/125, RAW.Tripod was slanted @ about 30°. Vertical correction in APG - thatÂ´s why the Nadir isnÂ´t in the center. That in no way does influence the panorama.

This again is the VR Drive II using my D90 with 10.5 fisheye. This is a before and after nadir. Using the VR Drive the nadir with this gear is very small so easily fixed in Photoshop using a patch. I did not capture a nadir image. I did not use the clone tool ether.. I will post a D800 nadir later...

yes, it's shot using a "normal" lens. for my Oly that is the Leica 25mm f1.4since the lenses in the MFT system are rather small I don't think it would matter much if I'd used the 12mm or the 8mm fisheye.I'll check it out some day later

DoesnÂ´t matter at all as long as the Nadir-hole is smaller than the base of the head . . which DestinyÂ´s example demonstrates most impressively

Also yours and mine examples show the tripodÂ´s base - so a smaller Nadir than the base itself wouldnÂ´t give any advantage.

I realize the smallest Nadir-hole on a sphere when i use my 105 mm lens. Here the downlook-angle is the steepest one i have shooting a sphere.And because of that the Nadir-hole using the 105mm is the smallest one.

Using the 8mm fe the hole will be larger.

When your head produce a small footprint it matters how you align it vs tripod, tripod legs, knobs, cables etc.I will do a comparison fisheye vs normal lens some day. I don't expect them to be very different in the case of MFT system.

ItÂ´s not depending on the sensorsize but on the focal-lenth COMBINED with the sensor size.

A 10,5mm on 1,6 crop is about the same as a 15mm on fullframe. So their Nadirs should be comparable - because of the lens-positionon the head which defines the downlook-angle in relation to the focal-length. The steeper the angle the smaller the Nadir.

This is the nadir (down face of a cube) of my Nikon D700, 14-24mm f/2.8 lens @ 14mm, on a Panoneed head and Really Right Stuff TVC-34L tripod. I'm using a leveling base between the tripod and Panoneed, no ball head or center column, so it sits very low on the fulcrum for very good vibration dampening and stability outdoors and in the wind. It also means the tripod legs stick out a bit further in the nadir, but it's quite manageable. I'd lose the ease of leveling and stability if I added the optional center column, not to mention getting 4" off the deck for low wide angle shots without the robotic head (which I often do). Stitching with this thing is near flawless! I only miss the manual rig on long hikes. Robotic heads are darn heavy!

I don't typically retouch in Photoshop for interiors. I usually use PTGui Pro and viewpoint correction with an off-axis nadir. Largely because I shoot a lot of tiled floors with multiple light sources, white balance, and glare. Photoshop just doesn't clone all that very well. Outdoor nature/scenic shots of course are much easier to just clone it out in Photoshop.

To make more challeging, I am working on an example with a 50 mm lens and a newspaper on the floor. Who can make a nadir where we can read the newspaper, also in the nadir?

Hey Hans!

What about your test?

bestl Klaus

As Always, commerciall work comes first, lot of it lately.

But the test is going well, already have decent pattern, already able to read the whole newspaper on the floor.Hope to shoot a perfect pattern soon when business slows again. ;-)

Ok, thank you for letting me know you are not interested in the final pattern/technique.:rolleyes:
